[0020] The specific embodiments of the utility model will be further described below in conjunction with the drawings. Wherein same parts are indicated with same reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.
[0021] In order to make the content of the utility model more easily understood clearly, the technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Wherein same parts are indicated with same reference numerals.
[0022] As shown in Figs. 1 to 4 A kind of in-mold product torsion mechanism, including torsion mechanism installed between upper die and lower die, torsion mechanism includes fixed seat 1, side pushing sliding block 2, torsion punch fixed block 3, rotating shaft 4;
[0023] The fixed seat 1 is fixedly arranged on the lower die; the side push sliding block 2 is slidingly arranged on the fixed seat 1; the torsion punch fixed block 3 is fixedly arranged on the side push sliding block 2; the rotating shaft 4 is arranged in the torsion punch fixed block 3 and is rotationally connected with the torsion punch fixed block 3; one end of the rotating shaft 4 is fixedly connected with the torsion punch 5, and the other end is fixedly connected with the torsion driving block 6;
[0024] The side push cutting tool 7 is fixedly arranged on the upper die, and the side push cutting tool 7 is arranged at one end of the side push sliding block 2 away from the torsion punch 5; when the side push cutting tool 7 is lowered, the side push cutting tool 7 is in contact with the side push sliding block 2, the side push sliding block 2 is slid, and the torsion punch 5 is butted against the product;
[0025] One side of the torsion driving block 6 is provided with the torsion cutting tool 8, the torsion cutting tool 8 is slidingly arranged on the fixed seat 1; when the torsion cutting tool 8 slides up and down, the torsion driving block 6 is driven to rotate, thereby driving the torsion punch 5 to rotate; the torsion punch 5 is provided with the clamping groove 9 for clamping and fixing the product to be twisted; the product is clamped into the clamping groove 9, and the product is twisted by the rotation of the torsion punch 5.
[0026] The rotating shaft 4 is rotationally connected with the torsion punch fixed block 3 through a bearing; the fixed seat 1 is provided with a sliding rail, and the side push sliding block 2 is slidingly matched with the sliding rail.
[0027] Working principle: when the mold moves downward, the side push cutting tool 7 moves downward to move the side push sliding block 2 and the torsion punch fixed block 3 fixed on the side push sliding block 2, thereby driving the rotating shaft 4, the torsion punch 5 and the torsion driving block 6 to move forward; at this time, the product enters the clamping groove 9 in the torsion punch 5; when the mold continues to move downward, the torsion cutting tool 8 drives the torsion driving block 6 to rotate, thereby the torsion driving block 6 drives the torsion punch 5 to rotate, the torsion punch 5 twists the product, the torsion cutting tool 8 works on the torsion punch 5, thereby the product is twisted without scratch.
[0028] When the mold moves upward, the side push cutting tool 7 moves upward first, the side push sliding block 2 and the torsion punch fixed block 3 fixed on the side push sliding block 2 move in the backward direction under the action of the spring, thereby the twisted product is withdrawn; when the mold continues to move upward, the torsion cutting tool 8 drives the torsion driving block 6 to rotate, thereby the original state is restored. The mechanism is a pure mechanical structure, and the stability is relatively high.
[0029] The above is only a preferred embodiment of the utility model patent, and does not limit the utility model patent, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model patent should be included in the protection scope of the utility model patent.
